System-specific upgrade for Dell Inspiron

This 32GB kit contains two 16GB DDR4 SODIMM modules rated at 2666MHz with CL19 timings. It runs at 1.2V and uses unbuffered, non-ECC chips in a 260-pin form factor. The kit is built to match the specifications of the Dell Inspiron 15 5593 and Inspiron 24 5000 (5490) systems.

Suits owners of listed Dell models needing maximum

The upgrade fills both memory slots to reach the 64GB platform limit when two kits are used, or provides 32GB in a matched pair for dual-channel operation. It is not for desktop PCs that require full-size DIMMs, for laptops limited to 16GB total capacity, or for any system needing ECC or registered memory.

Two matched sticks enable dual-channel performance

Installing the pair together lets the memory controller run in dual-channel mode, which improves bandwidth over a single module. All installed memory will operate at the speed of the slowest module or the processor's maximum supported rate. A 64-bit operating system is required to address the full 32GB capacity.

Questions about this item

My Dell Inspiron 15 5593 has two SODIMM slots — do I need to remove the original sticks before installing this 32 GB kit?

The laptop supports up to 64 GB across two slots. To reach 32 GB with this 2 x 16 GB kit, both existing modules must be replaced.

If I keep one factory 8 GB module and add one 16 GB stick from this kit, what speed will the memory run at?

All installed memory will operate at the slowest module’s rating, so the 2666 MHz sticks will down-clock to match the original 8 GB module.

After fitting both 16 GB modules, how can I confirm the system is using the full 32 GB at 2666 MHz CL19?

Open Task Manager’s Performance tab or run CPU-Z; both will show 32 GB total, 2666 MHz speed and 19-19-19 timings.
